[Invited] Optimization of quasi-periodically ribbed structures to improve stealth and discreteness of underwater vehicles

Bertrand Dubus, Charles Croënne, Samuel Deleplanque, Anne-Christine Hladky

Acoustic stealth and discreteness of underwater vehicles are important issues in underwater acoustics. These vehicles are constituted of shells which are periodically reinforced by ribs. Acoustic fields radiated or scattered by such structures are strongly affected by phenomena related to this…

3D FEM analysis of high-frequency AlN-based PMUT arrays on cavity SOI

Wen-Juan Liu, Leming He, Xubo Wang, Jia Zhou, Wei-Jiang Xu, Nikolay Smagin, Malika Toubal, Hao Yu, Yuandong Gu, Jinghui Xu, Denis Remiens, Junyan Ren

This paper presents three-dimensional (3D) models of high-frequency piezoelectric micromachined ultrasonic transducers (PMUTs) based on the finite element method (FEM). These models are verified with fabricated aluminum nitride (AlN)-based PMUT arrays. The 3D numerical model consists of a…

Low‐loss broadband (DC to 220 GHz) S‐CPW to S‐CPS transition for S‐CPS coplanar probing

Abdelhalim Saadi, Marc Margalef-Rovira, L. Vincent, Sylvie Lepilliet, Christophe Gaquière, Philippe Ferrari

The practical issue of probing coplanar stripline (CPS) structures is addressed in this Letter. A compact slow-wave coplanar waveguide (S-CPW) to slow-wave CPS (S-CPS) transition was designed and fabricated in a 55 nm BiCMOS process of STMicroelectronics. The signal strips of the slow-wave CPW and…

Investigation of cross-coupling in piezoelectric transducer arrays and correction

Abdelmajid Bybi, Sébastien Grondel, Ahmed Mzerd, Christian Granger, Mohammed Garoum, Jamal Assaad

Cross-coupling in piezoelectric transducer arrays is an undesirable phenomenon which decreases the performance of these devices. Indeed, when one element of a transducer is driven, it generates parasitic displacement fields at the radiating surfaces of the neighboring elements, which changes the…

Passive guided wave tomography for structural health monitoring

Tom Druet, Arnaud Recoquillay, Bastien Chapuis, Emmanuel Moulin

In this paper is presented a baseline-free quantitative method for imaging corrosion flaws in thin plates. It only requires an embedded guided wave sensor network used in a fully passive way, i.e. without active emission of waves. This method is called passive guided waves to-mography. The aim of…

High Lateral Breakdown Voltage in Thin Channel AlGaN/GaN High Electron Mobility Transistors on AlN/Sapphire Templates

Idriss Abid, Riad Kabouche, Catherine Bougerol, Julien Pernot, Cédric Masante, Rémi Comyn, Yvon Cordier, F Medjdoub

In this paper, we present the fabrication and Direct Current/high voltage characterizations of AlN-based thin and thick channel AlGaN/GaN heterostructures that are regrown by molecular beam epitaxy on AlN/sapphire. A very high lateral breakdown voltage above 10 kV was observed on the thin channel…

Performance Evaluation of Multi-Carrier Modulation Techniques in High Speed Railway Environment with Impulsive Noise

Michel Saideh, Yamen Alsaba, Iyad Dayoub, Marion Berbineau

Multi-Carrier Modulation (MCM) techniques are considered as one of the main building blocks for future railway communication systems. This is due to their ability to handle spectrum scarcity and asynchronous communications dilemmas. In this paper, we evaluate the performance of different…
